Above typical for an SME line. The remaining gap is usually in performance — short stops no one logs.

How it's calculated

  1. 01Run time = planned production time − downtime.
  2. 02Availability = run time ÷ planned production time.
  3. 03Performance = (total units ÷ run time) ÷ ideal units per hour.
  4. 04Quality = good units ÷ total units.
  5. 05OEE = availability × performance × quality. 85% is the usual world-class reference; 40–60% is typical for an SME line that has never measured it.
